CAR-TRUCK.

To all whom it may concern:

Be it known that I, WALTER S. ADAMS, a citizen of the United States, anda resident of the city and county of Philadelphia, State ofPennsylvania, have invented a new and useful Invention in Car-Trucks, ofwhich the following is a specification.

The object of my invention is to provide a truck which is suitable forcars propelled by electric motors, which truck will be light, strong,durable and easy riding and suitable in every way for light cars, andparticularly cars with metallic frames. These, and other objects areaccomplished by my invention, one embodiment of which is hereinafter setforth.

For a more particular description of my invention, reference is to behad to the accompanying drawings, forming a part hereof, in which Figure1 is a side elevation of my improved truck, portions of the crossingsand the car body being shown in dotted lines; Fig. 2 is an enlarged viewof an axle box; Fig.3 is a sectional view showing one form of springcups with a coil spring mounted therein and the end of a leaf spring;Figs. 4 and 5 show a modified form of cops to gether with the connectedparts, Fig. 5 being a sectional view, taken on the line 55 of Fig. 4,looking in the direction of the arrows; Fig. 6 is a plan view of half ofmy improved truck; Fig. 7 is an end elevation of the same looking towardthe motor support; Fig. 8 is a plan view of the structure shown in Fig.2; and Fig. 9 is an enlarged view of a spring cap and one end of asemielliptic spring, a portion of a spring seat being also shown.

Throughout the various views of the drawings, similar referencecharacters designate similar parts.

My improved truck 1 is provided with the conventional wheels 2 and axles3, one axle and two wheels being required for each truck. At each end ofthe axle 3 is mounted an axle box 4 which may be of any suitable designas to the parts which are connected with the axle, and on its top it isprovided with a suitable spring seat 5 to carry an upwardly flaredsemi-elliptic spring, and adjacent to this seat and extending laterallytherefrom is a projection 6 which is perforated in a vertical directionto receive and Specification of Letters Patent.

support a pin 7 which is provided at its lower end with screw threads 8and lock nuts 9 on which rest a washer 10, which carries a coil spring11, which bears against the under side of a block 12 which is pressedthrough which a second pin or bolt 13 is passed. The bolt 13 is providedwith screw threads 1d, lock nuts 15, and coil spring 16 which pressesthe parallel bars 17 against the block 12 so that these bars arepivotally connected to the block and permitted to shift thereon with alimited movement which is always opposed by the friction caused by thetension of the spring 16. The bars 17 are suitably perforated so as tobe carried and connected, as above set forth, the perforations in thebars 17 registering with the horizontal perforations in the block 12.The other ends of the bars 17 are united by a bolt 13 and a block 12identical with what has been above lescribed, and this secondblock 12has a pin 7 extending therethrough, precisely as above described, exceptthat this pin 7 also passes through a bracket 18 instead of the projection 6 on the jam box. The bracket 18 is upwardly splayed and providedwith suitable seats 19 which are adapted to be fixed to suitablecrossings 20 of the car frame.

The, inner bars 17 on each side of the truck are connected by a suitablecrossing 21 which has laterally extending ends 22 secured to the bars 17by bolts 23 and its center is upwardly arched at 24 to carry the motorsupporting springs 25 and their supporting bracket 26 so that the motorwill be hung true with regard to the axle 3 of the truck. Each axle box4 also carries in its seat 5 a semi-elliptic spring 27 with its freeends extending upwardly, and each end is provided with a suitable seat28 for a coil spring, and is perforated to receive a pin 29, whichextends upwardly through the spring seat 28, coil spring 30 and cap 31where it is secured by any suitable device, as a cotter. The cap 30 isprovided with a suitable seat 32 which is adaptedto engagea crossso 11m:when the Wiil be cushioned mg with the sprri'igs 11 be cushioned by thein, so that under a} without re ai' l to the Lrws is oi 3d.
